You would have to look up somewhere the form of a memory reference.
www.intel.com could probably help.

However, if you have Binutils 2.8.1 or above, the assembler supports MMX
instructions, so you could probably do it directly. Note that I believe
there is currently a bug whereby it generates the wrong opcode for PADD. But
the port of 2.9 should soon be available.
